  • How a reliable freeze spray can fix circuit board issues

    You’ve spent hours working on your newest project. Blood, sweat and tears all went into the assembly of your prized possession and if something goes wrong, well, you don’t even want to think about that. The truth is, though, a lot can go wrong when assembling a circuit board. After all, it is a giant mass of insulators and copper traces packed in together that takes significant time and skill to plan, design and build properly. You can do a visual inspection to check for any issues, but it’s also important to do a physical inspection of the board, and a reliable freeze spray is great to have on hand.

    The MicroCare MCC-FRZA freeze spray is the best for the job. It is designed for low-temperature, nondestructive thermal testing of electronic components with minimal static generation. It works to instantly chill surfaces to -45 degrees Celsius or lower, which can test circuit traces for stress fractures or loss of continuity. This is a cheaper and faster alternative to the shotgun troubleshooting process of replacing parts in a trial and error MicroCare MCC-FRZAfashion, which we like to call the “hope and pray” option.

    This freeze spray is designed to keep both you and your circuit board safe. The product is non-toxic, nonflammable, ozone-safe and plastic-safe. Since this spray is specifically designed to be used on a circuit board, it won’t cause damage like other generic canned air sprays might. Using a spray not made for circuit boards could actually cause more damage than it prevents, which just doubles your sweat and tear production, and no one wants that.

    Having a reliable freeze spray in your work space could turn complex issues into simple fixes. A freeze spray allows you to locate an issue in your circuit board and eliminate it quickly and effectively. Check out the MicroCare MCC-FRZA freeze spray today and start working on that next project of yours.

     

  • The best presaturated wipes for circuit board cleaning

    If you’re familiar with the PCB stencil printing process, you know that it takes great care and precision. Stencil printing requires the use of three main materials: a stencil, solder paste and a printer. The solder paste is spread over the printer to establish electrical connections with the PCB. Sometimes a squeegee blade is used to apply the necessary force to spread the paste across the stencil and onto the PCB. In order to keep your printing process running smoothly, you need to clean your stencil, boards and tools regularly. While you can attempt to clean them by using your everyday household products, that might not be the best option.

    A man attempting to clean his boards before printing encountered this very issue. He asked, “What is the best solution for cleaning dust and debris from printed circuit boards? I currently use paper roll wipes, but upon inspection I still find particles on the boards.”

    Mike Jones, Vice President of MicroCare and a specialist in the field of electronics cleaning and stencil printing, encouraged everyone that experiences this type of issue to get rid of the cheap paper wipes and switch to a lint-free presaturated wipe. “Presaturated wipes are desirable because they remove operator errors from the wiping process,” Jones said. “Every wipe is exactly the same, and carries exactly the same amount of solvent, so the cleaning can be very consistent.”

    MicroCare MCC-MLCW

    That is why MicroCare developed the MCC-MLCW MultiTask Surface Cleaner Presaturated Wipes. This product works to remove solder paste, flux residues, finger prints, uncured epoxy residues, light oils and grease from your surfaces before printing. Like Jones recommended, these wipes are lint-free and also won’t rip during use. The packaging has a unique “slam shut” design that ensures a long service life.

    The Techspray 1608-100DSP IPA Presaturated Stencil Wipes are another great option for SMT surfaces. They can be used to remove all types of solder paste and other adhesives from screens, misprinted boards, stencils, tools and equipment. These wipes are comprised of 70%  Techspray 1608-100DSPIPA and 30% ionized water, and are also lint-free. They are safe to use on plastics, have a two-year shelf life, and are non-ozone depleting. Having a dependable cleaning wipe at your disposal is important to achieve the best printing results and ensure maximum production.

    Both of these products can be found right here on the GoKimco website at an affordable price with fast shipping. GoKimco is a proud supplier of many other MicroCare and Techspray products, so be sure to check them out!

  • The five parts of the MicroCare Circuit Board Cleaning Kit

    Who doesn’t love kits? For less money, you receive a variety of products that were specifically picked to work together. The MicroCare MCC-CBCSK Circuit Board Cleaning Station Kit is no different. In today’s blog, we’re going to dissect all five pieces included in this kit, and why they’re all essential pieces to add to your work space if you frequently clean circuit boards.

    1. MCC-ESD Trigger Grip Cleaning System

    This is the heart of this kit and the main focus piece. This system makes circuit board cleaning faster and produces less waste. The amount of cleaning fluid use is reduced by 66%, cleaning the board in seconds and thus producing a safer work environment while cutting cleaning costs. It is reusable and ESD-safe.

    1. MCC-SPR High Purity Flux Remover Cleaning Fluid

    The MicroCare kit also includes a clear liquid heavy duty flux remover that comes in a 12 oz. aerosol can. This nonflammable and ESD-safe liquid removes grease, acrylic conformal coatings and instant drying flux with low odor and no residues. Its compatibility with the Trigger Grip Cleaning System is why it’s included in the kit and a great flux remover for circuit boards.

    1. MCC-RBNB Natural Bristle, Short Nose Trigger Grip

    The short nose trigger grip with natural bristle is designed with a flow-restrictor to reduce solvent flow and is highly economical. The brush can be removed and replaced with a number of alternative brushes if desired.

    1. MCC-BK3 Bench Mount Kit

    The bench mount kit works to hold the aerosol can and trigger grip neatly at your workbench. It prevents any of the solvents from tipping or falling over, extending the life of the trigger grip and ensuring the aerosol can will empty completely.

    1. MCC-WF44 High-Performance Lint-Free Dry Wipes

    The last product included in this kit is a pack of 50 high purity, lint-free polyester wipes. The wipes are 4” x 4” and each one can typically be used between 10 and 20 times before disposal. You won’t find any glues, bleach or cellulose on these wipes, which means you won’t have to worry about it degrading end-faces. The chemical makeup of the wipes makes “wet-dry” cleaning fast, easy and consistent.

    One piece is good but all five pieces of this kit together are great. Click here to add it to your work space for a discounted price today. GoKimco is a proud seller of many MicroCare products, so be sure to check them out.MicroCare Trigger Grip Cleaning Kit
